4 shows how signals are transmitted and received between the spatial remote controller 201 and the image display apparatus 100 when the spatial remote controller 201 and the image display apparatus 100 are paired according to the first embodiment of the present invention.

In the first embodiment, the spatial remote controller 201 and the image display apparatus 100 can transmit and receive signals through the management frequency channel. Information on the management frequency channel is stored in the storage unit 270 of the spatial remote controller 201 or the storage unit 175 of the image display device 100. [ The spatial remote controller 201 can refer to the information on the management frequency channel stored in the storage unit 270 and request the pairing to the image display apparatus 100 using the management frequency channel according to the referenced information. Using the management frequency channel, the spatial remote controller 201 can transmit and receive signals according to the RF communication standard with the image display apparatus 100 even before the pairing is performed.

The control unit 280 of the spatial remote controller 201 refers to the information on the management frequency channel stored in the storage unit 270 and transmits the pairing request signal to the image display apparatus (not shown) through the RF module 221 of the wireless communication unit 220 100).

The image display apparatus 100 receives the pairing request packet transmitted from the spatial remote controller 201 through the RF module 152 included in the wireless communication unit 151 of the image display apparatus. In response to the received pairing request packet, the image display apparatus 100 transmits a signal including information on a frequency channel that can be paired to the spatial remote controller 201 (S20).

The spatial remote controller 201 receives information on a frequency channel that can be paired by the image display apparatus 100 through the RF module 221 of the wireless communication unit 220. The spatial remote controller 201 scans a frequency channel included in the transmitted frequency channel information (S30).

The spatial remote controller 201 selects an optimal frequency channel as a pairing frequency channel as a result of the scanning. The optimal frequency channel selects the frequency channel that best receives the data or has the highest power (S40). That is, the spatial remote controller 201 can select a frequency channel having the highest reception sensitivity. In addition, the spatial remote controller 201 can select a frequency channel not used by another external device as a pairing frequency channel. Also, the spatial remote controller 201 can set a frequency channel having the least noise or interference phenomenon to a pairing frequency channel.

The spatial remote controller 201 transmits information on the selected channel to the image display apparatus 100. [ The image display apparatus 100 sets the pairing frequency channel according to the received channel information, and the pairing of the spatial remote controller 201 and the image display apparatus 100 is ended (S60).

When the pairing ends, the spatial remote controller 201 enters the RF mode (S70). The RF mode is a mode for transmitting and receiving a signal in accordance with the RF communication standard with the image display apparatus 100. In this embodiment, the controller 280 of the spatial remote controller 201 recognizes the mode of the spatial remote controller 201 as an RF mode if the information on the pairing frequency channel is stored in the storage unit 270. [

In this embodiment, the spatial remote controller 201 may be in an RF mode or an IR mode. When the spatial remote controller 201 is in the IR mode, the spatial remote controller 201 can transmit a signal to the IR module 153 of the image display apparatus 100 according to the IR communication standard. The amount of power consumed when the spatial remote controller 201 is in the RF mode is larger than when it is in the IR mode. Therefore, in the present embodiment, the space remote controller 201 is reset or enters the IR mode when no button or key operation is performed for a predetermined time or longer.

The user can control the image display apparatus 100 through the spatial remote controller 201 in the IR mode. For example, the user can operate the power-on button of the image display apparatus 100 among the buttons included in the user input unit 230 of the spatial remote controller 201. [ The spatial remote controller 201 in the IR mode transmits a power-on signal to the IR module 153 of the image display apparatus 100 according to the IR communication standard. The video display device 100 receiving the power-on signal is powered on.

In addition, even when the user does not use the space remote controller 201 for a long time, the space remote controller 201 can enter the IR mode.
